METAL WEATHER STRIP FOR STEEL CASEMENT WINDOWS AND DOORS Filed Feb. 1, 1956 INVENTOR Jab: Candles Patented Jan. 5, 1937 UNITED STATES PATENT OFFICE METAL WEATHER STRIP FOR STEEL CASE- MENT WINDOWS AND DOORS Application February 1, 1936, Serial No. 61,878

8 Claims.

This invention relates to new and useful improvements in a metal weather strip for casement windows, doors, and the like.

The invention has for an object the construc- 5 tion of a weather strip which is characterized by a one piece strip having an outer portion shaped to be resilient, an inner portion to support it, a portion extending substantially at right angles to said inner portion, and several double O layer hook portions for anchoring the strip and holding a felt anchorage strip.

More specifically, the invention contemplates a construction wherein all the various hook portions and the other portions are formed from one 5 strip of material continuously bent.

A feature of the invention is the fact that the portion which is disposed at right angles to the inner portion is formed with opposed hook portio-ns adapted to clamp the edges of the felt or 20 other similar strip.

A further object of the invention is the use of adhesive to attach the felt strip on a window frame and so prevent the passage of air, dust, dirt, and the like. At this point attention is called to the fact that if the weather strip is secured upon the frame with screws or fastening elements it is possible for air, dirt and dust to pass between the parts.

Another object of the invention is the con- 30 struction of a weather strip as mentioned which is simple and durable and which may be manufactured and sold at a reasonable cost.

For further comprehension of the invention, and of the objects and advantages thereof, ref- 35 erence will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a ma- 40 terial part of this disclosure:-

Fig. l is a front elevational view of a casement window with metal weather strips according to this invention.

Fig. 2 is a horizontal sectional view taken on 45 the line 22 of Fig. 1.

Fig. 3 is an enlarged detailedview of a portion of Fig. 2.

Fig. 4 is a perspective view of the metal weather strip per se.

50 p In Figs. 1 and 2 a casement Window is shown comprising a sash l and a frame H. The sash is supported by several hinges l2 so that it may swing open or closed. The frame is provided with the conventional edge piece Ha adapt- 55 ed to receive the conventional complementary edge piece Iliia of the sash. The sash is provided with several panes of glass I l secured in position with putty G5 or similar material. The window is adapted to be locked by a latch I6 swivelly mounted on the sash and adapted to engage in a locked position with a portion thereof extending over an edge of the frame member Ila. This invention relates merely to the weather strip which is interposed between the sash l0 and the frame II when the sash is closed. This weather strip 16 is secured upon the side member Ila of the frame.

The weather strip, according to this invention, comprises a strip having a curled edge por- I tion 29 forming a resilient hem from which a sharply outwardly inclined portion 2| continues.

A shallow inwardly inclining portion 22'continues from said outwardly inclining portion 2|.

A double layer hook 23 continues from the inwardly inclining portion 22 and connects with a base portion 24. This base portion continues into a double layer hook 25 at right angles thereto.

The double layer hook continues into a wall portion 26 substantially at right angles to the base portion 24. This wall portion continues into a double hook 21 opposed to the hook 25. The double hook terminates in an edge 28 located on the outside face of the wall portion 26.

A felt strip 29, or similar fastening strip, ex- 30 tends over the outer face of the wall portion 26 and is held in position by having its edges clamped by the hook portions 25 and 21. Cement 30 is interposed between the outer face of the felt strip 20 and the side of the frame member 5 Ha for mounting the weather strip in position. The hook 23 engages over the inner free edge of the side member I la, as clearly shown on the drawing, particularly Fig. 3.

When the sash is closed it strikes against a portion of the inwardly inclining portion 22, as clearly shown in Fig. 3. Preferably, it strikes the halfway area. Consequently there is a certain resilient action between the portion 22 and the sash. The hem 20 and the outwardly inclined portion 2I- supplement the resilient tendency of the inwardly inclining portion 22. At the other side the inwardly inclining portion 22 is resilient by reason of being connected with the hook 23.

An important feature of the invention is the cementing of the 'felt strip 29 upon the side of the frame I la which prevents dust and dirt from passing between these parts. To assist in the proper mounting of the weather strip on the frame the wall portion 26 and the base portion 24 are manufactured to have normal positions slightly greater than Consequently, when the strip is engaged on the right angle portion of the side member lla it will exert a pressure between the outer face of the felt 29 and the side of the frame member Ha.

While I have illustrated and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes; and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:
